The Sound of Quality

The JBL GTO series speakers are the perfect upgrade to your existing speakers. They are designed with a carbon-injected cone material to accurately reproduce music the way the artist originally intended. The three ohm voice coils allow the speaker to operate at an efficient 4 ohms once they are being powered, allowing them to utilize every watt of power your head-unit or 4ohm stable amplifier can produce. These speakers feature a vented magnet with a high thermal-capable voice coil which effectively dissipates heat, ensuring the longevity of your investment. The edge-driven speaker cones allow greater sound levels with the same amount of power. The wide frequency responses that these speakers provide will leave your ears very satisfied when you're listening to your favorite songs. If quality is your goal, the GTO series speakers by JBL have the technologies to make that happen.

Speaker Specifications

Series
This is the manufacturer product line of speakers.
GTO (JBL)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
3-1/2"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1"
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Cloth
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Carbon Composite
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Butyl Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
75 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
25 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
91 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
85 - 21000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
1-3/8"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
1-1/2"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
3-1/8" x 3-1/8" 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
No

Partial Review - Tweeters Only

October 31, 2013

I purchased these to change out the Bose "premium" speakers in the dash of my 2014 Altima 3.5SL. These speakers do NOT fit in the corners of the dash. I did this myself and only had so much time to finish this on a Saturday. The factory corner speakers are only tweeters. I thought these JBL speakers had the "pivot" feature that I have seen on other JBL/Infinity speakers, so I tried to twist the tweeter. It dislodged from its mounting and was just hanging by the leads! So I decided to chop off the tweeters and use them by themselves to do an even-swap with the original speakers. So this review is on the tweeters only. Wow! Clear, accurate highs. So much more open than the Bose. I listen to acoustic guitar and classic rock. SuperTramp "School" is my test song along with Acoustic Alchemy which I have listened to for years. I know these songs, and these tweeters deliver very accurate sound. For what it's worth, I can recommend part of this speaker. I will install one of the complete speakers in the center speaker spot (it is a 9-speaker system so I had to buy an extra pair to get an additional speaker for the center.) I will post another review for that later (when I get time to install it).

Mega Mids

February 16, 2014

First off I'm a die hard JL fan, Silverado currently houses XR 6.5 components in each door with a 10 inch w3 to give it a bassline. All speakers are backed by JL slash series amps to give it a very clean sound. I had a very treble Happy center stage and prominent low notes but I was missing the "fullness" to tie it all together. I installed the 3.5 jbl gto's in the center of the dash right below my deck and supplied them with power from my 300\4. Essentially after tuning I had created a 3 way component set, my sound is now incredible. Now when I crank it up it sounds like I have the whole band performing in my cup holders. So far I have no complaints, if your looking for a a set of small speakers to add some mega mid to your system I highly recommend these drivers.
